Air core coils

An air core inductor is nothing but copper wire with no core, so it never saturates and adds no distortion at any level. That is why it is the reference choice for passive crossovers, from tweeter circuits to bass filters.

The price is size and DCR: at high inductance the wire length and resistance grow quickly. Choose the thickest wire that fits; 1.4 mm or heavier wire cuts losses in the bass section considerably.
